This article will explain how the Files & Folders Tab works in your Advanced Tab in Muse Mosaic.
The folders' section corresponds directly to your sessions folder. Instead of changing the different folder paths from the various tabs (if you do not wish to use the default folders from your session), you can change the file paths directly from here.
Here, you can locate all the different files used by the mosaic and also directly change the file from here by clicking on the file path instead of navigating through the software to the different tabs to change each file. If you hover your mouse over them, the digital image display box will display the current file that is selected to be used by the mosaic.
